FLASHING AND FASTENING STRIP FOR ROQFS.

1,218,931 specification of Letters Patent.

Application filed October 4, 1916. Serial No. 123,737. To all whom it may concern:

Be it known that I, CHARLES E. HEARD, a citizen of the United States, residing at lVashington, in the have invented certain new and usefullmmovements in Flashing and Fastening Strips for Roofs, of which the following 1s a specification.

My invention relates to the construction of buildings and more particularly to means applicable to a variety of purposes, as for instance for use on all roofs and ledges where flashings are required to prevent the entrance of moisture and for securely fastening metallic roofs and preventing such roofs from becoming loose and blowing off.

Among the objects in view is to provide a simple, inexpensive and eflicient means adapted for flashing purposes and also for securing a roof of a building without danger of said roof working loose and blowing ofl and to avoid the use of nails and boards such as have heretofore been used generally, and said means being so constructed as to permit the expansion and contraction of the roof and to allow for settlement of the building.

A further object is to provide means as heretofore referred to which is adapted to be 'laid in the brick or stone-work while the latter is being erected and held permanently in place without the use of nails or boards.

A further object is to provide means as heretofore referred to adapted for securing flashings in position around any projection extending above the roof line and allowin for expansion and contraction of the roo and flashing.

A further object is to so construct the device that the same is adapted to quickly cut away the mortar or cement between courses of brick or stone when said device is to be inserted in position in old buildings.

Other objects and advantages of the invention will appear from the following-description when taken in connection with the accompanying drawings.

The invention consists in the novel construction of the device, all as hereinafter fully described, illustrated in the drawings and pointed out in the appended claims.

In the drawings:

Figure 1 is a vertical sectional view illustrating the invention as applied for securing a flashing around a fire-wall chimney or District of Columbia,

pther projection extending above the roof Fig. 2 is an enlarged perspective view, and Fig. 3 a sectional View of a portion of the device seen in Fig. 1.

Referring to the drawings, 15 indicates my dev1ce consisting of a strip made of any deslred metal, pre erably galvanized iron, and having any suitable length. The strip is bent longitudinally along the line 16 at a rlght angle, whereby to form the wide flange 17, and also the flange 18 which latter is bent or folded under and upwardly along the line 19 to form the portion 20, and the latter portion is then bent or folded downwardly to form an apron 21, which forms a groove 24 between it and the portion 20. The apron 21 is deeper than the portion 18, it extending between one-fourth and one-half an inch below the edge 19 to form a guide to facilitate the insertion of the bent-up edge of the roof or flashing.

The strip 15 is provided with a series of cut-away portions or recesses 22 to form teeth 23. These teeth enable the device to be used in the manner of a saw for cutting away mortar or cement betwen courses of brick or stone in old buildings by holding the teeth against the mortar or cement and then reciprocating the device whereby the teeth soo'n cut a mortise or slot of a depth sufficient to allow the flange 17 of the strip to be inserted in said slot. The device is then securely retained in place by pointing up the slot with mortar or cement.

When the device is to be afpplied on new construction,

I may provide said strip with a series of openings 24: of any desired outline and when the mortar or cement is laid upon the portion 17 it will enter said openings and orm keys when set.

The strip 15 is primarily intended for securing a flashing of a roof around a chimmy or other projection extending abme the roof line, as indicated in Fig. l, and also for use where buildings intersect.

In Fig. l I show the flashing 26 as being bent upwardly and extending within the groove 24. By this method of securing the flashing the latter cannot pull out and it avoids the entrance of moisture behind the flashing strip.

Also, contraction and expansion of the roof and settlement of the building are provided for. No soldering or nailing of the flashing is necessary and a saving in the cost of such nails and also in the labor involved is elfectecl.

The strip 15 is to be secured in place at any point above the roof line, preferably six inches or more.'

My device can also be used for fastening roofs securely, and when so used the roofing is bent over the outside of a wall and then downwardly, and its edge is then bent upwardly so as to enter the groove 24. In this manner the roof will be locked securely in position and cannot become loosened or blown ofi. Furthermore, this mode of fastening the roof avoids the use of nails, boards, laths, and mortar as heretofore used for the purpose and efl'ects a great saving in the cost of laying a roof.

What I claim and desire to secure by Let- ,v

ters Patent is:

A flashing comprising a strip having a wide flange for insertion between the courses of masonry, said flange having a toothed edge facilitating its insertion by a sawing action in masonry alread ing to prevent longitu al movement of the strip when built into a wall, and said strip also having a flange bent at an angle to the first-named flange and having a portion twice folded upon itself to form a de pending rib and an adjacent groove and then extending below the rib to form an apron.

In testimony whereof I aifix my signature in the presence of two witnesses.

CHARLES E. HEARD.
